· Input voltage: DC 5V, normally open interfaces, the max load of interface is AC 250V/10, DC 30V/10A.
· SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA.
· With green power light, red relay status indicator light, can reflect the module's working condition directly.
· The Module can be set by jumper high or low trigger.
The module uses genuine quality relay, normally open interfaces
Maximum load: AC 250V/10A, DC 30V/10A
SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA
The module voltage 5V
The module can be set high or low triggered by jumper
Fault-tolerant design, even if the control line is broken, the relay will not operate
Power indicator (green), relay state indicator (red)
Interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient
Module size: 50mm * 26mm * 18.5mm (L * W * H)
4 mounting bolts holes, hole 3.1mm, 44.5mm * 20.5mm spacing
DC +: positive power supply (voltage by relay requirements, 5V.9V.12V and 24V selection)
DC-: negative one
IN: can be high or low level control relay
NO: normally open relay interfaces, relay before hanging, pull back and COM short-circuited
COM: Relay Common Interface
NC: normally closed relay interfaces, relay and COM short-circuited before, after the pull-vacan
